Message To add to my post from last night about the car running great, then all of a sudden running on 5 cylinders, which initially gave me a code 34 when I got home but after resetting the codes it hasn't shown back up, and pulling #1 coil pack connector not causing any difference in idle sound...here's new info:

I tested the injectors at the ECU side, and the actual injectors (#5 and #6 were a pain to get to lol)

The first number is at the ECU at the very beginning, the 2nd number is at the actual injector, the 3rd number is re-testing at the ECU side.

#1-12.3 0 13
#2-12.2 11.6 12.9
#3-0 11.7 0
#4-12.3 11.5 13
#5-12.2 12.5 12.9
#6-12.1 11.5 12.9

I have no idea why pulling cylinder #3 coil pack connector last night changed the idle sound like the others, and it's showing no reading at the ECU twice but it is on the actual injector, and why #1 is showing a reading at the ECU twice but nothing on the actual injector. I am so confused.
